Special Thanks
This puzzle was made for the weekly Scojo Discord prompt, with a simple instruction: Collab with someone that you've never created a puzzle with before, pick a constraint each, and set!
I went out and secured a collab with lunchtime Twitch legend OlliWright!
Thank you Olli :) On behalf of both of us, we really hope you enjoy this puzzle.
Initial Setter Difficulty: 2.5-3 out of 5
Normal sudoku rules apply.
Place the digits 1-9 once each in every row, column and 3x3 minigrid.
Slow Thermometers
Moving along any grey line from bulb to tip, digits may increase or stay the same, but must not decrease.
Index Lines
On an index line, the digit in the Nth cell along the line (starting from the diamond) indicates the position along the line where the digit N appears. Eg: 3214 would be a valid line; the 1st digit, 3, indicates that the 3rd digit is a 1, and so on.

Optional Hint.
There are some key cells that see a lot of an index line that they must appear on. R8C2 is one such example.

Very cute, I like especially the impact the index line from box 6 to 2 had on the thermo. Thank you for the puzzle!
